These results are becoming positively commonplace, but it's always worth pointing them out, especially given that the broadcasters are still outrageously proposing to include the Liberal Democrats in two out of the three televised leaders' debates, but to wholly exclude the SNP and the Greens from all three. That plan looks more untenable by the day.
Britain-wide voting intentions (YouGov) :
Conservatives 32% (n/c)
Labour 31% (-2)
UKIP 17% (+1)
Greens 7% (n/c)
Liberal Democrats 6% (-1)
SNP/Plaid Cymru 5% (n/c)
In case you're wondering, YouGov don't differentiate between the SNP and Plaid in their GB-wide polls at all, although the vast bulk of the combined vote for the two parties can be assumed to be for the SNP (indeed it's perfectly possible that the SNP on their own would be on 5% anyway, after rounding).
You know the drill by now - a general election result that was even vaguely close to the figures in this poll would see the SNP becoming the third largest party in the new House of Commons, comfortably ahead of both the Liberal Democrats and UKIP. The Scottish subsample has Nicola Sturgeon's party on 49% of the vote, and Labour on just 21%. The fieldwork coincided at least partly with the confected "outrage" over the incident in Paisley, so it doesn't look like calling the SNP "Nazi book-burners" has done the trick for Labour any more than the Smith report itself did.

SCOT GOES POP POLL OF POLLS
No great surprise to see the SNP's lead increasing again in the Poll of Polls, because the outlying Populus subsample which had Labour ahead has now dropped out. This update is based on seven subsamples - four from YouGov, one from Populus, one from Ashcroft and one from ComRes.
Scottish voting intentions for the May 2015 UK general election :
SNP 43.6% (+2.6)
Labour 26.0% (-1.1)
Conservatives 15.6% (-1.0)
Liberal Democrats 6.3% (-0.7)
UKIP 4.6% (+0.7)
Greens 2.3% (-0.6)
(The Poll of Polls uses the Scottish subsamples from all GB-wide polls that have been conducted entirely within the last seven days and for which datasets have been provided, and also all full-scale Scottish polls that have been conducted at least partly within the last seven days. Full-scale polls are given ten times the weighting of subsamples.)
